News: The weird and the retro on this week's Nintendo Download.

Capcom's NES-style prequel to Dark Void, Dark Void Zero, will be added to the DSiWare service today. The "demake" will be joined by the DSi version of Chronos Twin, the puppy sim Me And My Dogs: Friends Forever and a tower defense game from Nintendo titled Starship Defense.

On the Wii side, one game will be added to the Virtual Console this week, Shadow Dancer: The Secret of Shinobi. The second Shinobi game will be joined by The Amazing Brain Train! on WiiWare and Muscle March. Allow me to let Nintendo explain Muscle March...

A bunch of bodybuilders (and a polar bear) clad in bikini briefs chase after protein-powder thieves who can bash through walls at will. Strike your best bodybuilder poses to catch the thief and make the protein powder yours again.

Wow. If you didn't already figure it out, Muscle March is the product of a Japanese developer. In this case, Namco Bandai.

More information on all of these titles can be found below.

As the '80s were drawing to a close, the developers at Capcom began work on a top-secret project that aimed to set new standards for the platformer genre. That game was called Dark Void. Alas, Capcom suspended development on Dark Void as it began to evaluate the SNES. Before long, the game was shelved and drifted, unnoticed, into the annals of gaming history. Dark Void became a legendary "lost project" at Capcom. Now, nearly 20 years later, Dark Void is back! To commemorate the game's humble origins, Capcom has commissioned this recreation of the original 8-bit classic, now re-titled Dark Void Zero, on the Nintendo DSi system. You play as Rusty, the first human born in the Void, who must take on the Watchers in a quest to stop their domination of Earth. With the aid of Nikola Tesla and his state-of-the-art rocket pack, Rusty must take down the Watchers and their minions across three intense levels of action and intrigue.
